Proton VPN is best evaluated as a transparency-forward VPN route layer. Its public materials emphasize Swiss jurisdiction, no-logs audits, open-source apps, Secure Core, and privacy-focused documentation. Those points matter, but they do not erase browser fingerprinting or account state.

Aerod verdict

Working verdict

Strong fit when transparency and public audit posture matter.

Proton VPN is a strong candidate when public audit material, open-source app positioning, and Swiss privacy posture are high priorities. It still needs DNS, WebRTC, and browser exposure checks after connection.
